Cosmological Tests of Coupled Galileons
Philippe Brax, Clare Burrage, Anne-Christine Davis +1
We investigate the cosmological properties of Galileon models with positive kinetic terms. We include both conformal and disformal couplings to matter and focus on constraints on t…
Linear perturbations in K-mouflage cosmologies with massive neutrinos
Alexandre Barreira, Philippe Brax, Sebastien Clesse +2
We present a comprehensive derivation of linear perturbation equations for different matter species, including photons, baryons, cold dark matter, scalar fields, massless and massi…
Small-scale Nonlinear Dynamics of K-mouflage Theories
Philippe Brax, Patrick Valageas
We investigate the small-scale static configurations of K-mouflage models defined by a general function of the kinetic terms. The fifth force is screened by the nonlinear K-…
Constraining Disformally Coupled Scalar Fields
Philippe Brax, Clare Burrage
Light scalar fields can naturally couple disformally to matter fields. Static, non-relativistic sources do not generate a classical field profile for a disformally coupled scalar,…
Cosmological tests of modified gravity: constraints on theories from the galaxy clustering ratio
Julien Bel, Philippe Brax, Christian Marinoni +1
The clustering ratio , a large-scale structure observable originally designed to constrain the shape of the power spectrum of matter density fluctuations, is shown to provide a…
K-mouflage Cosmology: Formation of Large-Scale Structures
Philippe Brax, Patrick Valageas
We study structure formation in K-mouflage cosmology whose main feature is the absence of screening effect on quasilinear scales. We show that the growth of structure at the linear…
